SergioChan opened a new pull request, #20833: URL: https://github.com/apache/datafusion/pull/20833
## Summary - fix planning for set-operation operands (`UNION` / `EXCEPT` / `INTERSECT`) when a non-left operand has repeated unnamed projection literals - on duplicate projection-name planning errors for non-`BY NAME` set ops, retry the right operand with deterministic synthetic aliases so output naming still comes from the left side - add a regression test for `SELECT 1 c1, 0 c2, 0 c3 UNION ALL SELECT 2, 0, 0` ## Testing - Not run locally in this environment (`cargo` is not installed here), so I could not execute the new test. ## Related Fixes #20818 -- This is an automated message from the Apache Git Service.
